Complementary angles.
Two angles that add up to 180 degrees are called supplementary angles.
They are called Supplementary angles,
Two angles that add up to 90 degrees are called complementary angles.
Those angles are called complimentary angles. They add up to 90 degrees. Two angles that add up to 180 degrees are called supplementary angles.
Angles that add to 180 degrees are called supplementary angles, while angles that add to 90 degrees are called complentary angles.
supplementary angles
Two angles that share a common side and add up to 180 degrees are called right angles and are 90 degrees.
They are called supplementary angles
They would be called "supplementary angles" because 90º + 90º = 180º and any two angles that add to 180º form straight, parallel, or congruent lines.(Angles that add to 90 º are called complementary.)
They are called linear pair, because their farthest sides lie on the same line.Any two angles that add to 180 degrees are called supplementary angles.
The angles are called supplementary if they add to 180 degrees. Where the two angles are adjacent, they form a "linear pair" such that their farthest sides lie on the same line.
They are supplementary angles that add up to 180 degrees
